Application filed .Tune 13, 1921. Serial No.l 478,604.

This invention relates to devices in which a combustible gas or vapor is produced from an oil. It is a well known fact that oils, and particularly petroleum oils, wh en highly heated, produce a vapor or gas which is inflammable, but it is diticult to prevent condensation of said vapor or gas and the attending accumulation. of carbon in the heating devices and to produce a gas or vapor which will be fully consumed without the formation of soot or smoke.

Many previous inventors have sougl'itto produce such a combustible gas or vapor by using steam under pressure to heat and atomize the oil. All such devices require the use of a steam generator or boiler. and are of no value in situations where steam is not available.

It is an object of my invention to provide a gas generator in which no steam is used and which will produce a highly inflammable gas without the accumulation of carbon in the generator. A further obj ect of my invention is to provide a generator which will form a. very perfect mixture of gas and air, and by which a very perfect combustion can oe produced.

`Wi th such objec-t-s in view, as well fas other advantages which may be incident to the use of the improvements, the invention consists in the procedure, and in the parts fand combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangements without departing from the nature of the invention.

In order to make the invention more clearly understood there are .shown iu the accompanying drawings means for carrying the same into practical effect, without limit-ing the improvements in their useful applications. to the particular constructions which for the purposeof explanation, have been made the subject of illustration.

Further objects and advantages will be made evident hereinafter.

Referring to the drawing which is for illustrative purposes only:

Fig. 1 is a sectional elevation on a plane represented by the line 1-1 of Fig. 2. v

' Fig. 2 is a section on a plane represented by the line 2 2 of Fig. 1.

Fig. 3 is a sec-tion on a plane represented by the line 3-3 0f Fig. 2.

Fig. 4 is a fragmentary sectional view taken on the vertical plane represented by the line 4-4 of Fig. 2. l l l Fig. 5 is a diagram showing course of air and gases.

As shown in the drawing, I employ air heating and vaporizing chambers, for example, the form of rings 11 and' 12 acting as circulating chambers in which air is` supplied through the pipe 13 and oil supplied through the pipe 14 absorb suflicient heat to accomplish the vaporization of the fuel oil.

The ring 11 is provided with a threaded oil inlet 20, a downwardly faced air inlet 21, and a downwardly faced mixture outlet 22 situated adjacent to the inlet 21. The oil line 14, which is cont-rolledI by a valve 23, enters the combustion chamber 25 in which the rings 11 and 12 are situated, through the wall 26 thereof, and rising therewithin makes screwed connection with the interior of the ring 11 through th'e inlet 2O and projects slightly within the passage 28 of the ring to provide an oil nozzle 29.

The lower ring 12 is similarly provided with an air inlet 30 and upwardly faced outlets 31 and 32. The air from a blower 35 to the ring 12 through the inlet 30. Connecting between the inl-et 21 of the ring 11 and the outlet 31 of the ring 12 is an air transfer pipe 37, and rising from the outlet 32 of the lower ring 12 is an L 40 which mounts an air nozzle 41 vertically extending tube; Downwardly project-ing from the outlet 22 of the upper ring 11 is a short nipple 45 having threaded thereupon a branch fitting' 50, the body 51 of which surrounds the upper portion of the nozzle 41 and is centralized thereupon by a bushing 52. A burner cap is threaded upon anipple 5G which extends upwardly from the body portion 51 of the fitting 50. K

The lblower 35 is driven from any source such as a motor and draws its supply of air from the surrounding atmosphere through a regulable intake 61 which is operated through a link connection 70 working between the control lever 71 of the valve 23, and an arm 7 2 extending from the damper cap 7 3 covering the blower intake. j

Air furnished by the blower enters the consisting ofa pipe 13 delivers air v lower chamber or hollow ring 12 as indicated by the arrowsV in Fig. 3 and assu-mes a divided course around the ring 12, part ol the air rising through the pipe 37 and entering the chamber or hollow ring 11, while the remaining air passes through thev arm l() and gains exit through the nozzle l1. A partition or obstructing web 58 separates the outlet 81 from the outlet 32 and entirely closes the interior of the hollow ring 12 therebetween.

The air stream enterine' the hollow rino 11- must necessarily take the course therein illustrated by the indicating arrows owing tothe presence of the obstructing web 80. A portionol the air rises through the pipe 37" flowing through the hollow ring 11 and a portion flows through the L l0 into' the air nozzle 41.

It will be understood that when the air is turned on, the oil is also allowed tof-'iflo-w owing to the'interconnected controls, this oil entering the'hollow ring l1 through the nozzle 29 is picked up by the air current and carried through the outlet 2Q .into the iitting 5G from whence it flows through a hole 85 in the wall structure oit the air nozzle lll, and iro-m the downwardly projecting portion 86 oi the nozzle -ll the oil drips through a hole 87 provided in a plug 88 into a lire pan ln starting the burner, ay quantity ot oil is i allowed to collect in the pan 89, and the oil' collected in the pan is their lighted. The flames from the burning oil heat the chambers or hollow ringsy 11 and v12 and the interjoining structure to a temperature suilicient to cause the vaporization oit any o-il coming in contact therewith. After the heating of the parts is accomplished, the air circulating through the hollow ring 12 becomes heated and from thencegpasses upwardly through the air passage 87 and the nozzle el. This air then entering the upper hollow ring 11 is subjected to still further heating action as it circulates therethrough, picking up the oil asit is excluded fromy the oil nozzle rl-he actionv of the air passing the nozzle 2D and the heated condition of the air stream causes the vaporizationy of the fuel which is then carried with the airinto the branch fitting 50. The air and the vaporizedv fuel pass up into the burner cap 51 where they are combined with the liow of heated air .from the nozzle 4:1 before being discharged through the oriiices 90 and 91 provided in the cap lt will be perceived that the orifices 90 are somewhat larger than the ori-lires 91 to providespreadingi llames proportionately greater tha-tthe rising llames. litter the burner is started a portion of the heat for vaporizationy derived from the radiated heat absorbed through the lower ring 12, while the greater amount of hea-t forr this purpose is gained in the upper ring l1 owing to the direct contact of the with the ring l1 That portion 27 of the oil pipe 14 which is contained within the combustion chamber 25 vpors is practically elimina-ted, therefor Leer/,rs1

is surrounded by a heat .insulating jaclret 95 to prevent the premature vaporization ot the oil in pas-zeilig therethrough.

As soon as the burner is in normal operation, the flow ot oil through the orifice ceases and heated air only is discharged through the critico-87, this air rising and supplying secondary air of combustion to the 'llame from the orifices 90.

Ey interconnecting the air and uel supply, l am able to simultaneously regulateboth. and lreep their ratio 'fairly constant.

The outstanding feature in the practical operation ot this burner generator is the almost compl ete absence of accumulated residue or carbon which is more or less prevalent in all previous oil burners known to me. l attain this previously unknown condition and eiiiciency through such an arrangement, assemblage and size of the burner parts and elements thatv condensation ol the heated vaall ot the vapors or manufactured. is consumed in the burner and goes to supply heat tor whatever purpose it is being, used. In coinparative tests my improved burner shown nearly double the eiliciency of competing burners ot equal size andv capacity on t-he same consumption of oil. In view of my experiments during the development of this invention and the tests above referred to, I consider the compactness and general arrangement ot the parts ofy thel burner, as shown, as going tar toward. permitting the results obtained, and therefor consider this hasarrangement and assemblage ot parts as alf very important part of my invention.

In my improved burner it will be noted that the passageways are quite large and unobstructed and theretor offer practically no resistance toA the `freek movement of the mc.- terials injected therein,V and owing4 to these largev areas the gas columns areeasily maintained at a comparatively uniform temperature, so there is practically no condensation and therefor no carbonization. Every particle-ot oil injected into my burner generator is consumed, except the base materials, which, by the intense co tinued heat are reduced to a very line ash which is being continually blown out ot the pipes through the burner orifices,l there is consequently no resi-- due ofi: any description present in. my burner generator alter prolonged period ot use. lt is `mainly due to this feature oli' my invention that l am able to attain such remarkable elliciency in comparison with other devices ot a like nature.

The invention is applicable in connection with other Jfuels than oils, tor example, or coal, especially coal containing considerable volatile material, such coal, for example, in powdered form, being injected, or otherwise introduced into the chamber 11. The chamber 11 constitutes not only a vaporizing chamber, but also a fuel and air mixing and heating chamber, the fuel'being mixer` by reason of the rapid circulation ofthe air through thefsaid chamber while the fuel is introduced thereinto.
